Radiator



.appena-ion 'flied 'imma 2e,

To all fic/'wm t 75mg/ Concern:

Be it known that l, THOMAS N. Cor- FELDER, a citizen of the United States, and

'a resident ot Cincinnati, in the county of Hamilton and State of Uliio, have invented certain new and useful Improvements in Radiators, of which the following is vlull, clear, and exact description, reference being| had to the accompanying drawings, forining,- a. part of tliis'specilication.

lily invention relates to imprm'einents in radiators and particularly to such radiators as Aare intended and adapted for use on motor vehicles.

lne ebjectet' niy invention is te provide a radiator of the character mentioned ot simple and inexpensive construction.

further object of iny invention is to provide .a radiator for motor vehicles 0i" great cooling eiciency.

Heretofore it has been the practice in sembling,r the core of a radiator' of the tubu` l: r type, to secure the tubes and fins together by means ol? soldering. it is the object of niy invention to provide nieans whereby the said parts may be assembled without the use oi solder to secure the saine together, thereu by siinplitvinp.` the construction and renden 30 'ing the radiator more durable.

A further object of iny invention is to provide in a radiator oi' the cliaif-cter inentioned radiating lins so constri ed that portions of said tins nia)Y alternate between vertically disposed tubes and present vertical front edges similar to the front edges ot said tubes, so that increased radiating efiicieucy may be obtained with a eoinpaia tivel \v small-number ottubes and still niaintain the unilforin and neat appearance of the radiator 'when viewed troni the front.

Further objects or' niy invention ivillappear from the followingy description thereof.

ln the drawings:

Fig. L'lis a perspective oi a inodiied Vlorin of radiating tin, witlra tube to show the manner of assemblage.

The numeral l indicates the upper tank and 2 the lower tank oi' a radiator adapted itil?. Serial No. 157,(59.

for use on motor vehicles. The said tanks orpany desired and suitable construction, oetween the said tanks l and f2 are vertically disposed tubes 3, the ends ot' said tubes being secured to said tanks in any suitable manner to prevent lealfige. ach of the tubes 3 is made a strip of sheet nietal, the said strip la i lded over and the edges soli` ered or ocliei v. Lse secured t0- getlier as shown l. The tribes as thus constructed, have but a 'sinvle se ni and the tube 'thus presents, along lfnii'e edge. ,f t regular intervals along the edges of the tube are not-ches Within which the radiatii'r iins are adapted to mounted in such a niauner that the edges oic the tubes and said lins will be in the saine plane.

` The numeral ll indicate he indiatii153,` iins of niy radiator. Yilach ot sud tins is cniposed ol a strip of slicet nieta, as 'lfor instance, copper, the saine being); provided with slots T at regular intervals throughout their length. The 'li-ont ends of said slots are narrowedl as shown at t3, and citcnd to points ucar the trout eilig-e i) of the iins. the distance between the slo and the edge of of lthe i-'it the iin baci; 5.o pcrniii the insia'iioii ot the tube. filter such insertion. llic portion lll is returned to its original positionA thus securingN i e lube in placel with the slot in engagement with -tlie 'iront odge ol" the lin. lietvwecu the slots in thc liu ari` folds forming lian s ll, the width ol' said llanc'cs being; approximately equal to the distance al *he llange Yroni the adjacent slots the liu being' equal to tli depth notches 5 in the edges -l o real' end of cach olf the lii assembling the core of ilic adiaior, a `suitable number ol i'ulics I are placed in 'llw slots T oi' the r quired uuu;I o oi' tins li, lliv notches 5 oi. lil i metal oil ille tins iii fi llic .said

uuaus ot' ille i, u al. 'li-oni edges olA to tubes aud las lie saine plane.

l lacs l s. allhoi said langes resistl u ysliou'n in Fig, 2 oi the d' i. heu 'thus asi-- seiublcd, as will be seen, the core, when ice vviewed from the front, comprises a series of vertical and horizontal edges in 'the same plane; alternate vertical edges being the edges of tubes, and those between being coinposed of i'ia'nges of the radiating tins, the 'whole presenting a uniform and neat appearance.

ln Fig. 4 l have shown a niodiied forni of radiating tin in which provision is made for double the number of tubes provide1 in the' form of core shown in Fig. 2, i"e flanges l1 being done away with. As so constructed, theI radiating iin is composed of a strip i2 provided with slots 13 of substantialljvv the. saine construction shown in Fig. 2, the .said slots however, being somewhat longer than the tubes to permit the insertion of same. lVhen inserted, and the notches 5") brought into engagement with the front edge of the fin, the rear portion of the fin is doubled over so that the rear edge abuts against the rear oi' the tubes thus securing the tubes in the slots, the front edges of the tubes being secured blv the notches The [ins when constructed either as shown in Fig. if', or Fig. i of the drawing may, if

desired. be provided with per-forations Me which add greatl)v to the radiating efficiency of said fins.

ifi-om the f/oregoing description, the nature and construction of new radiator will beapparent to those skilled in the art. `When constructed of tubes as above deA scribed and of radiating fins either as shown in Fig. 2l or Fig. Li, 'the parts may be-readily assembled withoutsoidering, and the core presents a uniform and neat appearance from the front. lnthe case/of the fin shown in` Fig; 3 however, .only aiternate vertical edges represent tubes,'whereas in 4the con'- struction disclosed in Fig. di, each of the vertical edges represents a tube. it wilibe noted that the construction of a radiator comprising the details above set 'forth is a matter ofgreat simplicity and of coirnparam tively small expense and labor. A radiator onstructed furthermore `in the manner 'above set forth `is of high radiating eilivprovided with a front knife edge and a Lessons radiation, and this construction is thus sub stantialiy as eticient as when an unbroken series of vertical -tubes is provided. The perforations la of the tins of course add greatly to the radiating eil'iciency thereof. rfi .radiator constructed substantialiy in accordance with the present invention, as will readily be seen by those skilled .in the art, may be. used also as a condenser for' steam cars and for similar purposes.

Ltiaving thus described muv invention, what I claim as new and desire to secure by Letters' atent is: l. A radiator core comprising a series of' fiat tubes having plain unbroken inner and outer surfaces and of a width to extend sul stantially from the front'to the rear of the i vided witha series of vertical fianges, anl

means whereb)7 said tubes and "fins may be assembled in such a manner that the tubes and thevvertical flanges alternate, and that said lianges on adjacent tins may register to present continuous edges correspcmding in appearance to the knife edges of the tubes.

3. in a radiator, a core comprising a series of vertical tubes each of said tubes being series of notches at'regular intervals in said edffe,

aseiies of radiating tins, each-of said hnsv comprising a strip provided with slots andy having a series of vertical flanges alternating with said slots, said slots .being arranged to receive said vtubes an'to engage in the notches therein so' that the front edges of sai-:l tubesy and fins will be d'sposed in the saine vertical piane Aand the flanges on adjacent tins will register' to present continu ous edges correspondii'ig in appearance to the front of the tubes.
